SPECIFICATION forming part of Letters Patent No. 506,963. dated October17, 1893. Application filed November 1, 1892. Serial No. 450,680. (Nospecimens.)

To all whom it may concern.-

Be it known that I, WILLIAM W. WORTH INGTON, a citizen of the UnitedStates, residing at Caldwell, in the county of Essex and State of NewJersey, have invented certain new and useful Improvements in Methods ofMaking Railroad Tie-Plates; and I hereby (1eclare the following to be afull, clear, and exact description of the same, reference being had tothe accompanying drawings, wherein- Figure 1, is a view of a portion ofa rail and tie, and an end view of a tie plate in position. Fig. 2, is aperspective view cf a tieplate. Fig. 3, is a perspective view of aportion of a bar adapted for making tie-plates,

, as is now well understood, should be sufficiently light to preservethe flexibility of the tie and avoid hammering, and yet sufficiently.

strong to avoid bending or buckling at the margin of the foot flange ofthe rail, and to meet these requirements the plates are preferablyformed with longitudinal ribs or projections on the under surface whichbrace the plate transversely of the rail and enter the tie in line withthe fiber thereof so as to avoid injury to the tie. Furthermore, suchtie plates should be provided with a series of lugs or projections upontheir upper surface to brace the foot flange of the rail, prevent itslateral movement on the tie plate and relieve the spikes from drawingstrains.

The object of my invention is the economical production of tie-plateshaving the general construction, or characteristics hereinbeforespecified.

To this end the invention generally stated consists in first forming atie-plate or bar more fully so that others skilled in the art to whichit appertains may apply the same.

In the drawings A, indicates the railway tie, B the rail, and C aninterposed tie plate.

The tie-plate C, will have upon its under surface one or morelongitudinal ribs 1, 1, which when the tie-plate is in position extendin the line of the fiber of the tie, transversely of the rail, and areof sufficient length to form a truss beneath the foot flange of rail B,and prevent the buckling or bending of the tie plate. Upon the uppersurface of said tie plate is also a series of longitudinally arrangedribs or projections 2, 2, and so disposed as to border on the rail seat3, and form abutments for the foot flange B of the railto resist thelateral movement of railB on the tie plate O, and prevent any drawingstrain on the spikes which secure the rail.

To economically produce a tie plate of the character shown, I firstproduce a tie-plate bar of the general form shown in Fig. 3

that is to say with a series of longitudinal ribs upon both faces-whichcan be conveniently accomplished by means of rolls having two or morepasses-as at a, b, Fig. 4- and subsequently remove sections 2 of theribs upon one face of the plate, to form the rail seat 3-by transverselyplaning the plate.

It is evident that tie-plates having the characteristics specified canthus be formed singly in an expeditious and economic manner, but thatfor purposes of manufacture it will be desirable to form the tie platebarin multiples of the tie plate, and subsequently sever the single tieplates therefrom.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

The method herein described for making railway tie-plates, whichconsistsin first form ing the plate with longitudinal ribs 011 bothpresence of two witnesses, this 26th day of of its faces, and thenplaning or cutting away October, 1892. parallel sections of the ribsupon one face of the plate to form the seat and abutments for WILLIAMWORTHm GTON' 5 the foot flange of the rail; substantially as Witnesses:

and for the purposes specified. WILLIAM L. FINDLEY,

In testimony whereof I affix my signature, in LOUISE A. BERNARD.
